文献和实验,那么哪种因素对模型贡献最大即与疾病联系最强呢? (InL(t-1)-InL(t)) 三种方法结果基本一致。 ③ 存在因素间交互作用时,Logistic 回归系数的解释变得更为复杂,应特别小心。 ④ 模型估计出 OR,当发病率较低时,OR≈RR,因此发病率高的疾病资料不适合使用该模型。另外,Logistic 模型不能利用随访研究中的时间信息,不考虑发病时间上的差异,因而只适于随访期较短的资料,否则随着随访期的延长,回归系数变得不稳定,标准误增加。 9.
Hints and precautions for the care, feeding and breeding of Neurospora
in heterokaryons. Auxotrophs such as inl and others affecting membrane components have short halflives in absence of supplement but show good survival if supplemented. I doubt that their long- term survival on silica gel has been determined.
Hints and precautions for the care, feeding and breeding of Neurospora
to advantage for sheltering and preserving difficult genotypes. Because osmotic stocks are readily lost, os stocks should be replicated and monitored or carried in heterokaryons. Auxotrophs such as inl and others affecting membrane components have short
